Hi, thanks for the report. This is not EAB. This is a common lookalike, the western cedar borer. It attacks and feeds on dead or dying western red cedar. It is not considered a pest. See #4 on ODA's EAB look-alike guide:

Here is some more info on western cedar borer and other woodborers from Oregon Department of Forestry:
